I've been using ppower4 for a while and it is great! For my next presentation, however, I would like to try a "fancier" style with background color (blue fading to black, with white and yellow text), because I've seen PowerPoint presentations using white on blue seems to be quite nice.
There is a problem with EPS figures, however as they now also have blue background and yellow lines (instead of black on white). It is nice sometimes but mostly not. I have to go back and change the colors I used to plot them (obviously I cannot use blue lines anymore). So I wonder if it is possible to: 1. Turn off background (and foreground colors) inside the figure region? or if that is impossible, 2. An easy way of switch back and forth between "fancy background" to "plain background" so I can use normal black on white pages for the figure? or 3. Any other options for background color? I took a look at pdfslide.sty and there it uses \overlay to implement arbitrary background. But I'm not sure that I want to go through the trouble of creating some background image. Michael
